description The utility model relates to a lever four-ball friction testing machine. The device comprises a console and a hollow workbench, the console is located on one side of the workbench. The workbench is provided with a grinding device and a lever loading device. A fixing sleeve and a piston circular truncated cone coaxially inserted into the fixing sleeve in a sliding mode are fixedly arranged on the upper end face of the workbench in a penetrating mode. The upper end face of the piston circular truncated cone is detachably connected with a four-ball oil box. Steel balls and lubricating oil to be detected are placed in the four-ball oil box; the lever loading device comprises a stress application lever of which one end is fixedly connected to the fixed sleeve and the other end extends out of the workbench, and a weight suspended at the end part, positioned outside the workbench, of the stress application lever; the middle part of the stress application lever is hinged with the workbench; aplurality of first circul
